فَتَقَطَّعُوٓا۟ أَمْرَهُم بَيْنَهُمْ زُبُرًا ۖ كُلُّ حِزْبٍۭ بِمَا لَدَيْهِمْ فَرِحُونَ
2:94.
Commentary:
It is a sad story repeated again and again in the history of every religion that after the departure of a prophet his followers begin to differ among themselves and become split up into sects and sections, every sect regarding itself as the true follower of their prophet and other sects as devoid of all truth, while the fact remains that every sect possesses some elements of truth. This is one meaning of the verse. The other meaning may be that the followers of every Prophet have always looked upon the followers of other religions as devoid of all truth while the truth is that all religions have proceeded from the same Divine Source and therefore their teachings possess a substantial measure of truth, though the whole and perfect truth is to be found in a religion which combines in its teaching all that is best in other religions. That religion is Islam.
After the death of a Prophet his followers generally begin to differ among themselves and split up into sects and factions, each sect regarding itself as his true followers and other sects as devoid of all truth.
